Double layer moulding processes for quality containers

The company has announced the introduction of a new moulding process that enhances the versatility of its lineup of one-step four-station injection stretch blow moulding machines. The new technology will provide ecological and aesthetic container manufacturing solutions.

MOULDING PROCESS

Previously, multi-layer preform moulding was used to improve container performance by inserting a thin layer of a secondary material between two outer body layers of the preform.

ASB’s newly developed double layer moulding process (patents pending) enables the container to be moulded with an inner and outer layer in the body section in a variety of thicknesses, configurations, moulding orders or resins. The aim of the new technology is to provide additional value and flexibility to the standard one-step ISBM process.

This method broadens container moulding options, not only in food safety, function and design, but also encourages increased manufacturing of ecological containers utilising recycled PET resin.

To enable this double layer moulding method, ASB developed a prototype machine named the ASB-12N/DL, which is similar in size to its existing small-scale ASB-12N/10 four-station injection stretch blow moulding machine.

This unit consists of five stations, with a second injection mould occupying the additional station being supplied by its own injection unit. The ASB Series one-step moulding process is well-known for its extreme versatility in moulding high-quality containers in a vast range of moulding resin. With the addition of the double layer moulding process, it is now possible to dramatically enhance the visual or physical properties using different materials for inner or outer layers.
